ATTACHMENT FOR COFFEE-URNS.

Application led November 11, 1919.

To all whom t may concern:

Be it known that I, JOHN N. SHAW, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented a certain new and useful Improvement in Attachments forCoffee-Urns, ofwhich the following is a specification My inventionrelates to improvements in attachments for coffee urns and moreparticularly to improvements in the cloth receptacle disclosed in mypending application for a coee urn, filed August 11, 1919, Serial No.316,890, and the object of my invention is to provide means on thecylindrical shell of the receptacle that is adapted to engage with meanson the cross-bar of the retaining member disposed within said receptacleto securely lock said member in position when the latter is seatedwithin the cylindrical shell of the receptacle to thereby positivelyhold the cloth in said receptacle in any fixed desired position.

With the above and other objects in viewwhich will appear as mydescription proceeds, my invention resides in the novel construction,adaptation, combination and arrangement of parts hereinafter describedand claimed.

I accomplish these objects by devices illus trated in the accompanyingdrawings, wherein- Figure 1 is a viewv in vertical cross-sectiony of areceptacle embodying the 'features of my invention, and

Fig. 2 is a top plan view of the same.

Referring to the drawings, f throughout which like reference numeralsindicate like parts, the numeral 5 designates ay tapered cylindricalshell, preferably formed of tin or similar metal, and adapted to beremovably suspended within the upper end of a coffee urn, not shown.

The shell 5 is provided at its bottom end with an upwardly curvedinternally projecting iiange 6 to thereby form an annular groove for thereception of the lower end of a cloth retaining ring 7, the latterhaving a diametrically disposed integral cross-bar 8` said cross-bar 8being provided with a central boss 9.

A stem 10 is disposed within an axial hole in the boss 9 and adapted forfree axial movement therein.

The lower end of the stem 10 is bent or Specification of Letters Patent.

Patented Feb. 17, 1920. Serial No. 337,239.

otherwise formed in the shapeof a. spiral foot 1l said foot 11 beingpreferably made of a smaller diameter than the ring 7 and adapted toengage with and distend, by its own weight, a cloth 12 of any suitablematerial in the form of a bag for the reception of the ground codec, asmore clearly shown in Fig. 1.

The size of the bag formedY by that portion of the cloth 12 that hangsbelowtlie shell 5 may be varied to suit the quantity of ground coffeethat is to be used therein by varying the amount of cloth that hangsbelow the said shell 5, theaforesaid portion being held distended by theweight of the stem l0 slidably mounted in the boss 9 and the spiral foot11. 4

To supportand fiXedly retain the cloth 12 in any desired position theYupper edges of the cloth overlap the curved flange `6of the shell 5,the said edges'being disposed between and positively held'by the ring 7seating in the annular groove formed by the flange 6, thereby securelyclamping the cloth 12 in the aforesaid desired position.

The ring-7 is pro-videdy on its upper end with a peripheral flange 18,the latter being adapted to fit snugly against theinner wall of theshell 5 to prevent water passing downwardly around the outer edge of thesaid ring 7.

To positively lock or clamp the retaining ring 7 in position, I haveformed on the inner wall of the cylindrical shell 5 adjacent to itslower'end thereof, an annular groove 14Cv adapted to beengaged bylocking members 15 carried bythe ring 7.

The locking members 15 are disposed on the upper face of the cross-bar 8and contiguous to the ends thereof, said members 15 being pivoted to thecross-bar 8 as by pins 16.

To facilitate the operation of locking and iuilocking the ring 7, I haveformed ears or wings 17 on the members 15, said ears 17 being preferablystamped out of the menibers 15 as it will be readily understood.

To assemble the elements comprising my device the cloth 12 is spreadover the spiral foot 11 with its edges lapping over the retaining ring7, the latter is inserted in the cylindrical shell 5 and presseddownwardly until the lower edge of said ring 7 enters the annular grooveformed by the curved flange 6, the locking members 15 are then turned toengage in the annular groove 14 to thereby securely clamp the ring 7 andthe cloth l2 in the desired position.

Manifestly, changes may be made in the forms, dimensions and arrangementof parts of my invention without departing from the spirit thereof.

What I claim is:

1. In a device for forming Ia bag of variable size from a' piece ofcloth comprising a cylindrical shell having an upwardly curved internaliange forming an annular groove therein and also formed with a groove onits inner side, a ring adapted to seat within said groove, a piece ofcloth arranged to be held between said fange and said ring and lockingmembers carried by said ring adapted to engage said last named groove tolock said ring to said shell.

2. In a device for forming a bag of variable size from a piece of clothcomprising a cylindrical shell having an annular groove therein, 1a ringadapted to seat in said groove, a piece of cloth adapted to be heldbetween said annular groove and said ring,

a stem slidably disposed within said ring, a

spiral foot disposedupon the lower end of said stem and adapted toengage and dis- ,tend the said cloth and locking means carried by thesaid ring to engage means on the said shell to' lockfsaid ring to saidshell.

3. In a device for forming a bag of variable size from a piece of clothcomprising a cylindrical shell having an upwardly curved internal flangeforming an annular groove therein, a ring adapted to seat in saidgroove, a piece of cloth having its outer portion secured between saidring and said curved liange, means slidably disposed withinl said ringand projecting downwardly therefrom and adapted to engage said cloth!and locking members carried by said ring to engage means on said shellto lixedly secure said ring to said shell. l

Ll. In a device for forming a bag of variable size from a piece of clothcomprising a cylindrical shell having an upwardly curved internal angeforming an annular groove therein, a ring adapted to seat within saidgroove, a piece ofk cloth adapted to be secured between the said flangeand the said ring, locking members carried by said ring to engage anannular groove formed on the inner wall of the said shellV to lock thesaid ring to the said shell and a stem slidably disposed within saidring adapted to engage and to distend the said cloth in a bagshapedformation. Y

5. In a device for forming a bag of variable size from Ia piece of clothcomprising a cylindrical shell having an upwardlycurved internal flangeforming an annular' groove therein, a ring adapted to seat within saidgroove, a piece of cloth adapted to be secured between the said flangeand the said ring,rlocking members carried by said ring to lock the saidring to the said shell and a stem slidably disposed within said ring andan integral spiral foot formed on vthe lower end of said stem adapted toengage andjdistend the said cloth in a bag-shaped formation.

6. In a device for forming a bag of vari able size from a piece of clothcomprising a tapered cylindricalshell having an upwardly curved internalflange forming an annular groove at the lower end ofthe said shell, aring adapted to seatwithin said groove, a cross-bar on said ringperpendicular to the plane thereof and Vhaving' an axial alined holetherein, a stem adapted for axial movement in said hole, an integralspiral foot formed on the lower end of said stem in a planeperpendicular to the aXis of said stem, a cloth disposed around saidspiral foot and adapted to be lixedly secured betweensaid ring and saidshell and clamping means carried by said ring to engage means on saidshell to clamp the said ring to said shell.

In witness whereof, I hereunto subscribe my name this 5th day ofNovember A. l).
